Hi my uncle's comp seems to be infected with a program called "windows repair." I've tried to remove the program using the tutorial from bleepingcomputer (Link) but to no avail. I was able to run the rkill program to stop the "windows repair" program, but every time I tried to run malwarebytes I got this error:

An error has occured. Please report this code to our support team.PROGRAM_ERROR_MISSING_FILE (2, 0, mbamcore.dll)The system cannot find the file specified

As well as

RUN TIME ERROR '53':FILE NOT FOUND: MBAMCORE

ACCESS DENIED

The LOG I got from the rkill program is:

This log file is located at C:\rkill.log. Please post this only if requested to by the person helping you. Otherwise you can close this log when you wish.

Rkill was run on 04/08/2011 at 21:16:31. Operating System: Microsoft Windows XP

I also tried to run combofix, but every time it finishes the screen is blank and the log isn't posted. Which leads me to believe the program never finishes. It always gets to the "Combo fix is finishing and preparing log file" yet when it closes, I just get a black screen with no icons and just the mouse cursor. I can see that it's trying to and or deleting the windows repair file because I can see it do so in the process but I'm afraid the program just doesn't quite finish. When I reboot the computer the windows repair program is still intact.

Yes, when I try to reinstall malwarebytes I get the same error. The machine already has malwarebytes on it because I've used it in the past.

When I try to remove malware bytes in the add/remove program I get this error:

Internal Error: Cannot find utCompiledCode record for thsi version of the uninstaller

When I try to just install using the installer again, I get the same error I get from my first post.

I can't run any programs, when I go to start menu > programs, it shows up as empty. When I try to click on the installer again it says the system needs to be restarted for malwarebytes to finish installing.
